network, a team that supports CO or LSO and is bound to a Hyper-V
virtual network reports CO or LSO as an offload capability in BACS.
However, in both instances CO and LSO do not work. This is a
limitation of Hyper-V because this system does not support CO and
LSO in an IPv6 network.
Teamed Network
Adapters
The following Broadcom team types are supported with Hyper-V:
Smart Load Balancing and Failover (configured only for one primary
and one standby)
Link Aggregation (IEEE 802.3ad LACP)
Generic Trunking (FEC/GEC) 802.3ad Draft Static
When configuring a team of NetXtreme II network adapters on a Hyper-V
system, be aware of the following:
Create the team prior to binding the team to the Hyper-V virtual
network
Create a team only with an adapter that is not already assigned to a
Hyper-V virtual network.
A TOE-enabled team that is bound to a Hyper-V virtual network reports
TOE as an offload capability in BACS; however, TOE doe not work.
This is a limitation of Hyper-V because this system does not support
TOE.
In an IPv6 network, a team that supports Checksum Offload (CO) and
Large Send Offload (LSO) and is bound to a Hyper-V virtual network
reports CO and LSO as an offload capability in BACS. Also, in an IPv6
network, a team that supports CO or LSO and is bound to a Hyper-V
virtual network reports CO or LSO as an offload capability in BACS.
However, in both instances CO and LSO do not work. This is a
limitation of Hyper-V because this system does not support CO and
LSO in an IPv6 network.
To successfully perform VLAN tagging for both the host (parent
partition) and the guest (child partition) with the BASP teaming
software, you must configure the team for tagging. Unlike VLAN
tagging with a single adapter, tagging cannot be managed by Hyper-V
when using BASP software.
Removing the
Device Drivers
Uninstall the Broadcom NetXtreme II device drivers from your system only
through the InstallShield wizard. Uninstalling the device drivers with
Device Manager or any other means may not provide a clean uninstall
which, in turn, may cause the system to become unstable. For information
on uninstalling Broadcom NetXtreme II device drivers, see “Removing the
Device Drivers” on page 82.
